South Denver Cardiology Associates (SDCA) recently began sending out data breach notification letters after the company disclosed that a data security breach was detected on January 4.

A subsequent investigation determined that an unauthorized person accessed the South Denver Cardiology network between January 2, 2022 and January 5, 2022. Sensitive files stored on the system were accessed.

In a notice on their website, the Colorado practice notes that there was no impact on patient medical records and no unauthorized access to the patient portal.

According to the announcement, a total of 287,652 patients were notified. The notice did not say whether the leaked files were from current patients or both current or former patients.

Based on the South Denver Cardiology investigation, the unauthorized party may have accessed the following personal data:
